To all whom it may concern:

Be it known that LHERMANN HAEBERLIN, a resident of Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Clutches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in clutches, the object of the invention being to provide improved means for locking the loose and fixed members together, which eliminates all sliding frictional contact, and the invention conslsts in certain novel features of construction and combinations and arrangements of parts as will 'be more, fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a right angle longitudinal sectional view illustrating my improvements. Fig. 2 is a Fi s. 3, 4, 5, 6, 7, 8, and'9, are views of detai s of construction, and Figs. 10 and 11 are views illustrating a modification.

1 represents a shaft on which a cup-shaped member 2 is loosely mounted, and power may be taken ofi from the hub portion of this loose member, in any desired manner.

3 represents thefixed member of the clutch, which is keyed to shaft 1 and located in the cup portion of member 2. I A friction plate 4 is screwed into the open end of cup or loose member 2, and is provided with grooves, in any of which, a screw 5 may be projected to lock the friction plate at any adjustment,

, and sockets 6 are provided in friction late 4 forming wearing surfaces, and serving to dis- I to receive a, spanner to adjust the p ateto any degree of fineness. A screw 8 closes an opening in member 2, throu h which lubricant may be supplied to the c utch.

The fixed member 3 is provided at diametrically opposite points with longitudinal grooves to receive keys 9, locking friction disks 10 to turn with'member 3 but free to slide thereon.- These friction disks 10 are provided with insert plates 11, ofhard metal,

tributethe pressure throughout the disks, and the disks are made with inwardly projecting lugs 12, having flat inner faces, for a purpose which will hereinafter appear. The

. -fixed member. 3 is also made,'at diametrically. opposite 'pointswith. longitudinal '13 outward, and swinging levers 16, causing grooves receiving sliding bars 13 connected The bars 13 are made with openings to re.-

- ceive studs 15, having rounded heads lying in recesses in the ends of semi-circular arms or levers 16, the latter straddling member 3, and provided between their outer ends with blocks or carriers 17 made rigid with said arms or levers and located between the friction disks 10. Blocks or carriers 17 are madehwith longitudinal bores or openings forming casings for a number of balls or rollers 18. Three balls or rollers are shown, although any number, preferably an odd number, may be employed. The outer ends of the arms or levers form curved shoulders at the sides of the blocks or carriers 17 and these curved shoulders rock on bearings which the lugs 12 provide.

In the position shown'in Fig. 1, the balls are tightly pressing the friction disks 10 against the loose member 2, to lock the latter. to the fixed member 3, and compel them to turn together. To release the clutch, sleeve 14 is drawn outward, thus drawing the bars the curved shoulders formed by the ends 0 the latter to rock or roll on lugs 12 of disks 10. The block or carrier is thus caused to rock or oscillate and change the angle of the line of balls with relation to shaft 1, and move the balls to the position shown in dotted lines; relieving pressure on the friction disks 10 to release the loose member. As the levers 16 swing, the balls will roll on each other and on the wearing plates 11, thus dispensing with any sliding frictional engagement during the operation of throwing the clutch in and out.-.

In assembling the clutch, a screw 33 is employed to secure the friction disks 10 together and hold them in proper alinement, but this screw is removed before the friction plate 4 is screwed into place.

In the modification illustrated in Figs. 10 and 11, I provide the clutch with four o erating levers 19, carrying bl ks 20, in w llOll latter the balls or rollers 2'1 re located, and moved against or away from the friction disks, as clearly shown. The sliding bars 22, at opposite sides of the fixed member 3, each operate two of said levers 19, and the bars 22 are moved by sliding sleeves 23. The outer ends of the levers 19 are made with rounded shoulders 24 movable on lugs 25 of the friction disks 26. In order to increase the transmitting power of this modified form of clutch, two friction 1plates 27 and 28 are inserted between the iction disks 29 and the loose member 30. Plate 27 is forced to rotate with fixed member 31 and plate 28 rotated with loose member 30, all of which is clearly illustrated in the drawings.

A great many other changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence, I do not restrict myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the s irit and scope of my invention.
